LONGITUDINALLY-DISPLACEABLE CAR-BODY FOR MOTOR-VEHICLES.

Specification of Letters Patent.

Patented Dec. 17, 1907;

Application filed January 25, 1907- $erialNo. 353.957-

To all 'whom it may concern:

lie it known that I, RUnoLF DiEsnL, asubject of the King of Bavaria,residing at Munich, Germany, have invented certain new and usefulImprovements in Longitudii'ially- Displaceable Car-Bodies forMotor-Vehicles, I of which the following is aspecification.

There are alreadymotor cars witliwhich the laying open of the drivingmechanism effectedby rearwardly displacing the car body or a part ofsame on guiding rails or slides; these constructions have the drawbacks,that the inev table soiling and rusting of the guiding rails or slidesgreatly cncumbers the use of the device, that if the guiding f rails arenot arranged exactly parallelly a squeezing takes place, and thatseveral men for assistance are required, Further disf advantages consistin the fact that the car around a hinge or joint fixed to the car frame;

body cannot be shifted in the whole length fromv the car frame, thus thepurpose being only partially achieved, and that on wholly removing thecar body, either supports for supporting the part hanging over are re- 1quired or it is necessary to put the car body 1 com letely aside whichrequires much atten ance and space. Also such vehicles are known withwhich the car body can be tilted In the accompanying drawings, Figure 1r shows 1n side view a motorcar provided with g the new device, Fig. 2illustrates a detail.

The car bodya is provided with rolls 1) which are mounted approximatelyI in the vertical transverse plane passing through the center of gravity8 of the box. The rolls b may run on the longitudinal bars 0 of theframe or on particular rails. As maybe seen from Fig. 2, the rolls 1)are mounted on the car body on eccentrical journals 1) in such a mannerthat by-turnin'g a disk d eccentrical to the roll axis, by means of afixed or re. movable handle f the whole car body can be lifted for thelittle amount it from the frame 1 balanced car body. Zrequires the leastspace, and the driving c. \Vhen lifted, the car body can swing abouttheroll axis 1) (Fig. 1) ,and one man only capable to draw out the wholecar body in the direction oflthe arrow 'L Fig. 1.

The eccentric device shown in Fig. 2 for lifting the car body from theframe is only givenas an instance; this lifting can be operated by anyothermeans permitting a small displacement of the roller axles, such asscrews, wedges, levers or any combination of known mechanisms.

The supporting rolls 1) are arrested in the point 7c, Fig. 1, by hookshaped catch pieces,

and then the whole car bodymay be tilted into the position a thereby thecomplete driving mechanism being laid open.

After the car body has been brou ht again into its normal position, thediskd Fig. 2) is turned back, so that the car body a is replaced uponthe frame 0, and may then in ordinary-manner be fastened to itby screwsor other fastening means. Instead of arresting the rolls at the point7c, also the journals of the rolls or special journals adapted to thebox. in ay be held fast; or the rolls at both sides of v the car bodymaybe mounted upon a common.

axle transversely extending through the car body, which axlemay bearrested at the end of the car. The axes of the rolls lying ap--proximately inthe transverse vertical plane passing through the centerof gravity of the box, only one man is suflicient to effect thedisplacement as well the tilting of the fully Further this operationmechanism is completely laid open.

What I claim as new and desire to secure by Letters P atent, is

"In a motor car, a longitudinally displaceable car body, having rolls(1)), approximately in the vertical transverse plane passing through itscenter of gravity, said rolls being swingingly or otherwise movablymounted on the car body for enabling a lifting of the car body from theframe, and catch .picces, (k), mounted on-the rear end of theunderframing and arresting the rolls (b) when the car body, after havingbeen displaced, is tilted towards the rear side'.

In witness whereof, I have hereunto si ned my name in the presence oftwo subscri )ing witnesses. I

RUDOLF DIESEL.
